How does the composition of lymph differ from that of blood?
Weegy: Lymph is considered a part of the interstitial fluid, the fluid which lies in the interstices of all body tissues.[1] Interstitial fluid becomes lymph when it enters a lymph capillary. [ The lymph then travels to at least one lymph node before emptying ultimately into the right or the left subclavian vein, where it mixes back with blood. Lymph returns protein and excess interstitial fluid to the circulation. Lymph picks up bacteria and brings them to lymph nodes to be destroyed. Metastatic cancer cells can also be transported via lymph. Lymph also transports fats from the digestive system. The word is derived from the name of the Roman divinity, Lympha. ] (More)

Explain the effects of peripheral resistance on blood pressure
Weegy: In the cardiovascular system, there is an increased pressure leading up to the site of occlusion, but through the narrowed section of arteries, there is also an increased flow rate. Blood vessels, however, are not rigid, except in areas of occlusion. [ So, as pressure increases, so does the vessel volume, and eventually, the ventricle of the heart (left ventricle if the problem is in most of the body, right ventricle if the increased resistance is due to pulmonary obstruction). This begins to gradually work backward through the entire cardiovascular system. When the organs reach a point where they can no longer expand to accomodate the pressure increases, in the case of blood vessels, they may rupture (i.e., ruptured aneurysms), or in the case of the heart, it simply ceases to have the strength to continue beating. In either case, you die when it reaches that point (without immediate medical intervention). ] (More)

Why are valves necessary?
Weegy: valves are important because the prevent the backflow of blood. This is so the fresh oxygenated blood will not be mixed with the deoxygenated blood as well as the blood running from the pulmonary side will not flow back to the aortic side. [ The valves keep the blood going in one direction that keeps the body stable............... ] (More)
